In general, it seems like most people don't object to the idea in principle, but concerns are being raised around the transparency of the scheme, which so far has no civilian oversight, unclear backing legislation and an appeals process which does not exactly inspire confidence. Why is it those who want to implement this kind of filtering never quite address these sort of concerns up-front?
